COIKLBINA'I'ION TOOL.

Application filed September 20, 1921 Serial No. 501,973

fully described and represented in the ac,

companying specification and drawing, forming a part of the same.

This invention relates to an improvement in combination tools andhas'for its object to provide a tool unit which, while combining theuseful elements of various tools constantly required in automobile workor the like, shall be simple in construction and operation and,therefore, economical in manufacture, durable, and highly eflicient.This invention also has for its object to provide a novel wrenchconstruction as a part of such tool unit which shall be capable of easyand quick adjustment to the largest and smallest parts in automobilework or the like. and the construction of which wholly obviates theobjectionable feature of ive in wrenches of ordinary construction.

or the tool elements associated therewith,

With these and other objects in view, my invention in a preferredembodiment will now be described in detail by reference to theaccompanying drawing, in which sim ilar reference characters denotecorrespond ing parts and in which Figure 1 is a perspective view of thecomplete tool; Fig. 2

is a side elevation of one end thereof with the bail or hook shown incross-section;

r the members, as A, for instance, is formed with a raised or thickenedportion Shaving on its outer face a longitudinal row of notches or teeth6. Pivoted to the sides of the opposite jaw 4 as at 7 is a loopshapedmember, bail, or hook 7 capable of being passed around the jaw 3 andprovided centrally with a knife edge or tongue 8 which is adapted toengage any one of the notches or teeth 6. The notched or toothed portion5 is suitably curved as shown and so situated with respect to thepivotal point of the bail? that on shifting the bail from one end to theother of the curved surface .5 the jaws 3, dot the wrench will .beopened or closed. Thus in the extreme forward-position of adjustment ,of, ,thebail the jaws 3,

t r" the wrenelr will be opened} to their widest point, and when thebail in its extreme rearward positionsaid :jawswill be either entirelyclosed or opened to the smallest width, according to the previouslyselected shape and size of said curved surface 5.

To facilitate adjustment and use of the wrench and pliers a suitablespring 9-is preferably. mounted on the inner face of either one ofthemembers A, B with its free end normallypressing against the other memberand tending to separate the wrench aws. I I

.Each plier jaw may on its inner face he provided with cut-away notchedportions 1, 2 to form pipe-engaging jaws. plier jaws may be formed withthe usual wire cutters 11. t

hen it is desired t use only the pliers the bail 7 isswung entirely offthe jaw 3 of the cutter A. i

In the modification shown in Fig. 4:, which is the preferredconstruction, the jaw A has its thickened cam-shaped portion providedwith a longitudinal central slot 3 extending throughout'its entirethickness and length, and each lateral edge of said slot is toothedthroughout its length, as at 6. I The opposite jaw B is provided on itsinner face with a centrallongitudinally extending groove 4*. The bail 7is in form of a lever, the lower end of which bears in the groove 4 andis fulcrumed therein at 7". The upper end of said lever '7 extends thruthe slot 3 of the jaw A and has its free end broadened so as to form across-piece 7 which in length corresponds with the width of thethickened or cam-shaped portion of the jaw A. The lower edge of saidcross-piece is formed to a knife edge or tongue 7 which is adapted tocooperate with the two sets of teeth 6 formed at the lateral edges ofthe slot 3.

The operation of this modified construction is the same as that of thefirst-described construction.

It is understood that various modifications may be made in theconstruction of the device without departing from the spirit These of myinvention and I. therefore, do not restrict myself to the detailsdescribed and shown.

What I claim is having two sets of teeth along the edges of said jaw, 21second jaw having a groove, and a bail in form of a'le'ver fulcrumed insaid groove and adapted to project through a slot of the first-namedjaw, the free end said lever being broadened and formed with a knifeedge to cooperatewith said two sets of teeth in the adjustment of saidjaws relative to one another.

2. A tool unit comprising pivoted crossed members, wrench jaws formed onsaid members,one of said jaws havlng a cam-shaped outer surface and aslot extending through said jaw, two sets of teeth arranged along theedges of said slot, the opposite jaw hav- 1 ing longitudinal groove, anda lever piv- 1. In awrench, a cam-shaped slotted aw oted in said grooveand adapted to project through the slot in the other aw, the outer freeend of said lever being broadened and having a knife edge to engage saidteeth, so that by swinging said lever from one end of the curved toothedjaw towa-rd the other end, the jaws of the wrench will be adjusted tothe desired extent. y.

In Witness whereof, I have hereunto signed my name this 19th day ofSeptem ber, 1921.
